GEORGE MERRILL AND WILLIAM H. MERRILL, OF RIVERSIDE, MICHIGAN.

CAR-COUPLlNG@ SPECIFICATION forming part ef Lettere Patent No. 272,299,dated February is, Issa.

Application tiled December l2, 1882. (Nn model.)

To all whom it may concern: f

Beit known that we, GEORGE MERRILL and WILLIAM H. MERRILL, citizens ofthe United States ofAmerica, residing at Riverside, in the county ofBerrien and State of Michigan, have invented certain new and usefulImprovements in Car-Couplings; and we do hereby declare the following t0be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters or iigures of reference marked thereon, which i'orm a part ofthis specitication.

This invention relates to certain new and useful improvements incar-couplers; and it consists more especially in providingthe drawheadwith a spring, whereby the coupling-pin is held and forced into place,which spring also serves to depress the draw-head.

It also consists in the construction and combination ofthe parts,whereby the pin can be raisedV and the draw-head adjusted so as toaccommodate cars having draw-heads located at different heights, as willbe hereinafter more fully set forth, and pointed out in the claims.

In the annexed drawings, which illustrate our invention, Figure l is aperspective view, showing the draw-head attached to a car and thecoupling-pin raised and held in place by Figs. 2 and 3 are sectionalviews, showing the coupling-pins in different positions; andFig. 4 is adetailed perspective view.

A represents the beam or bumper, to which the draw-head is attached by apivot or bolt, a, and .this bumper A overlaps the sides of the drawheadB. The under side of the bumper A is pivoted with a cross-bar, c', whichprevents the draw-bar being depressed below the plane ot'thesame. Thisbumper A is provided with the usual springs and means for attaching thesame to the car, and its front end is curved for the reception oftherear curved end of the draw-head. The front end of the draw-bar B isprovided with the usual bell-shaped recess and vertical openings for thereception of the link and coupling-pins, and it is cut away on its upperportion for the reception of the plate l), which serves as a guide forthe coupling-pin and prevents the same being displaced. Longitudinaldisplacement o this plate is prevented by the raised ends b b of thedraw-head, and lateral by the side bars, E E, which fit into grooves orrecesses in the sides of said plate. spring, C, which extends over thedraw-head B and the plate D, by means of which the pin is forced andheld in place. The side arms, E E, which project above the draw-head B,extend upwardly and rearwardly, and they are connected to each other bythe transverse bar F. The coupling-pin is operated by a suitable lever,as shown; or there may be provided other means to elevate said pin,either from the top or sides of the cars.

The operation of our improved coupling and draw-head is as follows: Whenit is desirable to couple cars having draw-heads of the same height, theend of the lever is depressed so as to raise the pin to asufficientheight to alylow the link to enter the draw-head, and i whenin position, the lever being released, the

spring will force the pin in position by pressing upon the plate l), andin coupling cars of diiferent heights the pin is raised until the plateD strikes against the transverse barF on` the arms E E, and the leverbeing further depressed elevates the draw-bar 'to the desired height.

By the arrangement and construction of this coupling device, we make asingle spring operate both the coupling-pin and draw-head.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is p,

1. In a car-coupling, the combination ofthe bumper A, having pivotedthereto the draw` head B, with side arms, E E, transverse bar F, andplate D, carrying thecoupling-pin and operating means, substantially asshown.

2. The draw-head B, having"rearwardly-in clined side arms andconnecting-bar, in coinbination with the plate D, with recessed sides,substantially as shown. I

3. The bumper A, having curved front portion and transverse bar on itsunder side, and

Attached to the bumper Ais a spring C, in combination with the draw-headIn testimony whereof we afx our signatures B, with rear curved end audpivot a, side in presence of two witnesses.

arms, E E, bam F, and guide-plate D, attached to the eoupiiugfpin, andoperating means, substanbially as shown, whereby the coupling-pin i canbe raised and the draw-head elevated, for l the purpose set forth. l
